Roadside Mailboxes
– 4325
4-Wide Spreader with Newspaper Holders
on a Pedestal Installation Instructions
U.S.P.S. APPROVED
Installing Mailboxes on 4-Wide Spreader with Newspaper
Holders on a Pedestal
Thank you for selecting Salsbury’s 4325 roadside mailbox.
This instruction sheet is for installing 4325 mailboxes on a 4-wide spreader with 4315
newspaper holders and a pedestal. A different instruction sheet is available for
installing 4325 mailboxes on a 2-wide or 3-wide spreader with 4315 newspaper
holders and a pedestal. Other installation instructions are available for installing the
mailbox on a pedestal, or on a deluxe mailbox post, installing the mailbox on a
spreader, and installing the pedestal in a concrete footing.
When you install a curbside or roadside mailbox, make sure that it is easily accessible
to the mail carrier. By regulation a locked mailbox should be 41” to 45” from the
ground or street surface up to the point of mail entry. The door should be set back 6”
to 8” back from the front face of the curb or the road edge. However, you should
check with your local postmaster to ensure that the mailbox is installed according to
local regulations. It is important to note that it is not the responsibility of mail carriers
to open mailboxes that are locked, accept keys for this purpose, or lock mailboxes
after delivery of the mail.
Spreader Installation to Pedestal
All hardware to attach the spreader to the pedestal is included with the spreader. To
attach the spreader to the pedestal, install four (4) 5/16”-18 X 1” long hex flange head
bolts through the four (4) center square holes of the spreader and through the four (4)
tapped holes on the top plate of the pedestal. Cover the hex flange head bolts with
cap plugs.
Next install a support arm by installing four (4) 5/16”-18 x 1-3/4” long carriage bolts
through the four (4) square holes shown in the spreader and through the four (4)
corresponding square holes in the top plate of a support arm (supplied with spreader).
Install 5/16” flat washers and 5/16”-18 hex nuts on the ends of the four (4) bolts
protruding below the bottom of the support arm. Complete the installation of the
support arm by drilling a 3/16” diameter hole though each hole in the vertical plate of
the support arm and through the pedestal. Install 1/4” flat washers and 1/4” x 1” long
lag screws into the post. Cover the lag screws with cap plugs. Repeat these steps for
the other support arm.
Newspaper Holders Installation to Pedestal
All hardware to attach the newspaper holders to the spreader is included with the
spreader. To attach a newspaper holder to the spreader, install four (4) 5/16”-18 x 1-
3/4” long carriage bolts through the four (4) square holes in the inside floor of the
newspaper holder, through the 1/4” tall square spacer and through the four (4)
corresponding holes on the spreader. Install 5/16” flat washers and 5/16”-18 hex nuts
on the ends of the four (4) bolts protruding below the bottom of the spreader. Repeat
these steps for the other newspaper holders.
Mailbox Installation to Newspaper Holders
All hardware to attach the mailboxes to the newspaper holders is included with the
newspaper holders. To attach a mailbox to a newspaper holder, install four (4) 5/16”-
18 X 3/4” long carriage bolts into (4) square holes in the floor of the mailbox and
through the four (4) square holes on the top of the newspaper holder. Install 5/16” flat
washers and 5/16”-18 hex nuts on the ends of the four (4) bolts protruding below the
